'Sniper' rounds.

I've never bothered to make any, so I was just wondering: How many of you have made them?

Also, any tips on how to easily make them?

EDIT: I decided to make some, and they're a pain to make, but it's worth it. I got 217 ft. for range. I measured on google earth. Also, I found that if you do it right, you can use duct tape for the fins. I like the duct tape because it's sturdier, and doesn't bend or deform as easily.

i only shoot fin ammo w/ my TR i slightly angle the fins to rifle the rod in flight this keeps the rod stable in wind and prevent other variables from altering the rods path/trajectory i have vids on my TRIFLE page
